Yo iPhone app hacked

Yo, the pointless app that lets you message the word "Yo" to your contacts (and nothing else) has been hacked by a college student and his two roommates. The trio has been able to acquire any Yo user's phone number and spam them with multiple messages, though they opted not to abuse the latter discovery. Yo has confirmed the hack and promised a fix.
